ACCORDION.

Application filed June 17, 192?, Serial No. 199,489.

The invention relates toaccordions of the concert class having a pianokeyboard, and the object of the invention is to provide means wherebythe windchest and main portions of the accordion may be shortenedwithout reducing the length of the keyboard, thus materially lesseningthe weight of the instrument, or conversely the keyboard may belengthened without width of the'keys to be increased to facilitatefingering. The invention consists in certain novel features ofconstruction and arrangements of 1 parts by which the above objects areattained to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show theinvention as it has been carried out in practice. Figure 1 is a frontelevation of the improved instrument.

. Figure 2 is a corresponding plan view with a portion of the grillremoved.

Figure 3 is an end elevation of the keyboard and adjacent parts of theaccordion.

Similar reference numerals indicate the same parts in all .the figures.

The main parts of the accordion, comprising the lower register keys orp1ns 5, the bellows 6 and upper windchest 7, w1th its series ofreed-valves 8, the latter covered by an ornamental grille 9, a portionof which.

is shown as broken away iniFigure 2, may all be of the usualconstruction and proportions.

The ends 10 of the windchest 7 instead of being carried upward in linewith such ends to-form the ends of the keyboard casing asusual, areflared outwardly as at 11 to extend the keyboard 12 beyond the length ofthe windchest 7, as clearly shown in Figures 1 and 2. v 7

This arrangement permits thewhite keys 13 to be wider than is possiblein the usual form and the black keys 14 also to be correspondingly morewidely spaced, 'while atfording ample room for the rods 15 which of thekeys correspondingly 10 lengtheningthe body, thus permitting the jointhe keys to the reed-valves8 for operating the latter, thuspermittingthe widening while maintaining the usual ran e.

1%16 advantages of the wide keys in fingering the instrument areapparent, and will be greatly appreciated by musicians.

e improvement requires no increase in the size of the main portions ofthe accordion and the slight additional weight due to the small increasein the size of the keyboard casing and wider keys is negligible.Conversely, the main body of an instrument equipped with the usualkeyboard having keys of normal width, ma by this invention be reducedmaterially in size andweight and such instrument thus especially adoptedfor female and juvenile performers.

I claim 1. In an accordion having a windchest and reed valves, akeyboard having extensions, the keys of said extensions lying beyond theplanes of the ends of said windchest, said extensions connected to saidwindchest and thereby providing room for the connection's from theextension keys to their reed valves.

2. In an accordion having a windchest and reed valves, a keyboard havingextensions, means connecting the keys of the keyboard to the reedvalves, said windchest flared outwardly at the ends to accommodate theextensions of the keyboard and provide room for the connections betweenthe extension keys and their reed valves.

3. In an accordion having a windehest and redvalves, a keyboard havingkeys lying beyond the planes of the ends of said windchest, and meansconnecting said outlying portions of the keyboard to the windchest, andthereby providing room for the connections from said out-lying keys totheir reed valves.

In testimony that I claim the invention above set forth, Iaffix mysignature hereto.

ROBERTO PANCOTTI.
